COMPOSITE GAZETTEER OF ANTARCTICA

rising to c. 1600m between Handel Ice Piedmont to E and Purcell Snowfield and Vivaldi Glacier to W, W Alexander Island, were probably sighted from a distance by FAE, 1908-10, in January 1910, as the name Sommet Martine (Mount Martine, q.v.) was erroneously placed in this area (Bongrain, 1914, vue 44 following p.60); photographed from the air by RARE, 27 November 1947; called US Navy Range (AGS map, 1948); later named Colbert Range after Rear-Adm. Leo Otis Colbert, USN (1883-1968), Director, US Coast and Geodetic Survey, 1938-50 (Ronne, 1948b, map p.356, p.391). Mount Colbert (Ronne, 1948c, map p.198). Colbert Mountain Range, Colbert Range (Ronne, 1949, p.290 and end map). Navy Range, as rejected name (USBGN, 1949, p.11). Colbert Mountains (NGS map, 1957b; [in 70 35'S 70 35'W] APC, 1961, p.2; DOS 710, sheet 14, 1963; [co-ordinates corrected from USLANDSAT imagery of January 1973] APC, 1977, p.9; BAS 250P sheet SR 19-20/9, 1-DOS 1978).

Isolated mountain mass with several rounded snow-covered summits, the highest 1,500 m, overlooking Handel Ice Piedmont between Haydn and Schubert Inlets in the W central part of Alexander Island. First seen and photographed from a distance by Lincoln Ellsworth on his trans-Antarctic flight of Nov. 23, 1935, and partially mapped from these photos by W.L.G. Joerg. Resighted and photographed from the air by the USAS, 1939-41, and by the RARE 1947-48, under Ronne, who named it for R. Admiral Leo O. Colbert, head of the U.S. Coast and Geodetic Survey, which furnished equipment for the expedition. Remapped in detail from RARE air photos by Searle of the FIDS in 1960.
